Want to follow in Mark Zuckerberg's Facebook footsteps? Here's a start

Even if you recently considered quitting Facebook, or you already have, you might still wonder: How does Mark Zuckerburg do it?

You've heard all the rumors: He's a hacker, a dropout, and a naive or immature geek. But, he's also created something that has changed the world forever. The Palo Alto, Calif.-based Facebook, reportedly dreamed up by Zuckerberg and his friends in a Harvard dorm room in 2004, has spread far beyond its humble roots in a startling, short time period. Brands such as AT&T, Ford Motor Company and BlackBerry maker Research in Motion all advertised on Facebook during the first four months of 2010, according to Internet analytics firm comScore.

Facebook has even challenged Internet mega-players such as Yahoo and Google--a jaw-dropping accomplishment. In Decemeber 2009, TechCrunch predicted that Facebook could make a billion dollars in 2010. Information was leaked last month that Facebook's revenue in 2009 reached between $700 million and $800 million dollars, higher than some of the most generous predictions.

So criticisms and controversy aside, Mark Zuckerberg has done something from which most of us can learn a thing or two. What's the secret to Zuckerberg's success?
